 after waxing. This insures more uniform results. 



Grafting wax, a formula for which will be 

 given presently, is usually applied several inches 

 below the crack which was made for the cleft in 

 which to insert the cions. 



In some cases, however, the stock will later 

 crack below the point where the grafting wax

 of the graft dying. For this reason it is wise to 

 examine the grafts and where any open crack is 

 found, additional wax should be applied. 



There are various modifications of the cleft
